DYNAMICAL ANALYSIS OF BANDA SEA CONCERNING WITH EL NINO, INDONESIAN THROUGH FLOW AND MONSOON BY USING SATELLITE DATA AND NUMERICAL MODEL

---

Banda sea is subjected to external force such as El Nino South Oscillation (ENSO), Indonesian Through Flow (ITF) and Monsoon. All of these component Combined with Current System, caused sea dynamic. This study aimed to get further knowledge about Banda sea dynamic. Based on this phenomenon , this study was conducted with an hypothesis that sea level anomaly (SLA) and sea surface temperature (SST) will decrease during ENSO event. Also that SLA and SST will seasonally change concerning with Monsoon. The pattern of current in eastern of Banda sea will be seasonally different concerning with monsoon while in western of Banda sea is almost constant according to ITF This research carried out in Banda Sea within the rectangular region from 122.42 E to 131.47 E , Latitude 03.47 S to 07.65 S. in period of 1996 to 2006 consist of northwest monsoon, southeast monsoon, 1st transitional month in April and 2nd transitional month in October. Spatial analysis used to analyze annual and seasonal distribution of SST and SLA from satellite dataset, also by comparison between wind data, ITF pathway and numerical model. SST derived from NOAA / AVHRR satellite data by applying MCSST algorithm, SLA derived from Topex/ Poseidon and Jason-1 Satellite data by applying Inverse distance weighted interpolation, while numerical model derived from barothropic model using Princeton ocean model. Sea level anomaly and sea surface temperature is decrease according to ENSO event, such as decrease of SLA and SST during ENSO event in 1997 , 2002 and 2004. Sea level anomaly and sea surface temperature is change according to Monsoon. SST and SLA get maximum level during northwest monsoon in November to March and get Minimum during Southeast monsoon in May to September. There are strong correlation coefficient between annual Sea level anomaly and annual Sea Surface Temperature with index value up to 0.817104. on the other side correlation coefficient between seasonal Sea level anomaly and Seasonal Sea Surface Temperature is 0.576469. Based on Pattern of current we found that Western part of Banda sea is strongly affected by ITF while eastern part of Banda sea is strongly affected by monsoon.
